AEROPLANE.

Specification of Letters Patent. Patented Sept. 21, 19290 Application filed Noyeinber25, 1919. Serial No. 340,456.

To all whom it may concern:

Be it known that we, PAUL T. WOLFE and WILLIAM H". BOVARD, citizens of the United States, and residents of Los Angeles, in the county of Los Angeles. and State of California, have invented a new and Improved Aeroplane, of which the following is a full, clear, and exact description.

This invention relates to improvements in aeroplanes, an object of the. invention being plane which will quickly ascend in "a substantially vertical line and which can be operated to start and light without the necessity of running over the ground.

A further object is to provide an improved construction and arrangement of rotary.

planes which are caused to move in opposite directions and are located substantially at a horizontal.

A further object is to provide a plurality of pairs of planes with improved means for imparting rotary motion to the pairs of planes to turn them in opposite directions. A further object is to provide improved means for elevatingand propelling an aeroplane. I I

With these and other objects in view the invention consists in certain novel features ofconstruction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings-- Figure 1 is a view mainlyin side elevation but partly in section illustrating our inven .tion; and

Fig. 2 is an enlarged view in longitudinal section through the driving mechanism.

1 represents a vertical post supporting a pair of tubular telescoping shafts 2 and 3 thereon, the shaft 2 being appreciably longer than the shaft 3 and extending above the same. A basket or car 4 is secured by stays I tween the same and "shaft 3.

5 to a collar 6 mounted loosely on the shaft 3 and having ball bearings 6 located bea fixed collar 7 on the .':;'1he. post 1 is secured at its lower end to a -motofl 'base8 and above its lower end is made in the" form of' a ring 9 receiving a motor 10. Suitable frames 11 and 12 are supported in the basket or car 4 and in the upper portions of these frames 11 and 12, shafts 13 and 14 respectively are mounted. The shafts 13 and 14 are normally horizontal and in alinement and the shaft 14 carries an ordinary propeller 15 to move the aeroplane hori zontally.

The shafts 13 and 14 are provided with beveled pinions 16 and 17 respectively which mesh with beveled gears 18 and 19 secured to shafts 2 and 3' respectively. A motor shaft 20 is provided with a sprocket wheel 21 connected by asprocket chain 22 with a sprocket wheel 23 on shaft 13 so that motion is transmitted from the shaft 13 through the pinion 16 to drive the gear wheels 18 and 19 in opposite directions and transmit motion to the pinion 17 and shaft 14 to turn the propeller 15. v

The shafts2 and 3 at their upper ends are provided with brackets 24 supporting horizontal arms 25 projecting in opposite directions. The arms 25 are normally horizontal and the arms 25 of the shaft 3 are located appreciably lower than the arms 25 of the shaft 2. These arms 25 support planes 26 which are concave on one side and convex on the other side and are made up of'suitploy two or more pairs of planes projecting laterally in opposite directions, one pair located above the other. The planes of each pair are reverselypositioned so that when the shafts are turned, the concave faces of the planes are always the advanced'faces so that the rotary motion imparted to the planes has a tendency to elevate. The operation is as follows: As above explained, the shaft 13, through the medium of the pinion 16, turns the gear wheels 18 and 19 in opposite directions. As these gear wheels are fixed to the shafts 2 and 3 respective ly, the planes 26 are caused to move in a circular,"normally horizontal path and the lower planes are moved in a direction opposite to the movement imparted to the upper pair of planes. This movement of the planes insures an elevation of the aeroplane in a substantially vertical line andthe speed of such elevation is in accordance With the rotary speed of the planes. It is therefore apparent that by decreasing the speed of the planes, the device may maintain any desired elevationinthe air or may be allowed to quickly descend, and while We illustrate a propeller 15 which is connected directly by the shaft 14 and pinion 17 to the gears 18 and 19, it is obvious that various other expedients may be resorted to to exactly control the movement of the aeroplane in the direction of flight.

Various slight changes may be made in the general form and arrangement of parts described Without departing; from the invention, and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

e claim:

post projecting upwardly'from the car, tubular shafts on the posts, rotary planes projecting laterally from the vertical tubular shafts, frames on the car projecting upwardly from the car, alined shafts in said frames, means for transmitting motion from 1. An airship, comprising a car, a vertical shafts to turn the latter in opposite directions, means for transmitting motion from the tubular shafts to the other horizontal shafts, a propeller on one of said horizontal shafts, and means for transmitting motion to one of said horizontal shafts.

2. An airship, comprising a car, a vertical post projecting upwardly from the car, tubular shafts on the posts, rotary planes projecting laterally from the vertical tubular shafts, frames on the car projecting upwardly from the car, alined shafts" in said frames, ,a pair of beveled gear Wheels on the tubular shafts, horizontal shafts supported in the frames,pinions on the horizontal shafts meshing with the beveled gears, a propeller on one of said horizontal shafts, a motor supported in the car, and means for trans- Initting motion from the motor to one of said horizontal shafts.

3. An airship, comprising a car, a vertical post projecting upwardly from the car and having a ring portion at its lower end, a motor mounted in the ring portion, hori-* zontal rotary planes mounted on the post, means for turning the planes, and meansfor transmitting motion from the motor to the planes.
